GOLD-SEPARATING MACHINE.

SPECIFICATION forming part Of Letters Patent N0. 674,533, dated May 21, 1901.

4 Application filed April 7, 1898. Serial No. 676,840. (No model.)

To all whom it may concern.-

Be it known that I, JOHN BROYLES, a citizen of the United States of America, residing in the city of New Whatcom,Whatcom county, State of Washington, have invented a new and useful Gold-SeparatingMachine,of which the following is a description.

This invention relates to gold-separating machines, and has for its object the provision of novel means for separating sand and other foreign substances from the gold.

With the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail reference will be had to the accompanying drawings, formingpart of this specification, wherein like characters denote corresponding parts in the several views, and in which- Figure 1 is a side view of the machine; Fig. 2, a top view thereof. Fig. 3 is a longitudinal sectional view. Fig. 4 is a detail view of the tripping mechanism for the shaker-box, and Fig. 4 is a sectional view of. the magnetic cylinder. Figs. 5, 6, and 7 are detail views of one of the cylinders.

In the drawings, 1 indicates a frame suitably supported, having in and crosswise of its bed a. an elongated reservoir 2 at one end, a reservoir 3 at the opposite end, and reser- Voirs444 equidistantly placed approximately midway of its length, said reservoirs 4 being semicircular in cross-section. The reservoirs 4 are formed in a bed-plate 5, and plates F are supported by the bed-plate in any suitable manner. The plates F have tongues or teeth, preferably V-shaped, struck therefrom.

Near the inner end of the elongated reservoir 2 a hollow metal cylinder Ois journaled to bearings 8 on the sides of the frame. Inside this cylinder 0 are secured in any wellknown manner a number of magnets 9. Also secured to the side of the frame is a scraper B, made of a non-metallic substance, such as wood, said scraper being concaved down Wardly and having one edge bearing against the cylinder 0.

Over the reservoirs 4 and j on rnaled in bearthe same construction as the cylinders dand below the plane of the other cylinders) isjournaled in bearings about midway the height of the sides of the frame. An approximately semicircular plate 14, secured to the bed of the frame, passes under the cylinder A and has a flared portion n entering a shaker-box M, suitably placed.

All of the cylinders have spindles 17 and 18 projecting on one side, on which are wheels 71., connected by belts or sprocket-chains r for a purpose plainly apparent. To the spindle 18 is secured a trip-wheel K, and to the side of the frame is pivoted a lever Z at 24. On the free end of the lever is an antifrictionroller 25, bearing against the trip-wheel. guide 26 for the lever is also secured to the frame. A short distance from the pivoted end of the lever Z is fulcrumed a second lever, 0. The opposite end of the lever 0 ispivotally secured to the shaker-box M.

The cylinders are vertically adjustable in their bearings by means of the slots and screws, as indicated at 28.

Power for operating the machine is derived from any suitable source. as follows: Ore is put in the reservoir 2 and quicksilver in the reservoirs 4, and the cylinders are adjusted to the desired height. The magnetic surface of the revolving cylinder O collects the black sand and other for- 85 supply of fresh quicksilver by means of the 0 teeth, amalgamating the fine particles of gold as the ore is forced along and depositing it between the outer or perforated plates and the inner or solid plates. The surplus sediment is deposited in the shaker-box M, and 5 its discharge therefrom is accelerated by the tripping mechanism.

It is to be noticed that all of the plates are made of sheet-copper and coated with silver to hold the amalgam and prevent corrosion. 100

The operation is The construction and operation of the device will, it is thought, be fully understood from the foregoing.

It is to be remembered that details in the construction and arrangement of parts may be resorted to that fairly fall Within the scope L of the invention and claims.

Having thus fully described my invention, what I claim as new, and desire to secure, by Letters Patent, is

1. In combination, a frame having an elongated reservoir at one end, a second reservoir at the opposite end and a series of reservoirs semicircular in cross-section equidistantly placed midway of its length,doub1e bed-plates secured to the frame between the reservoirs, cylinders journaled vertically adjustable in the sides of the frame and over the reservoirs, perforated plates on certain of the cylinders, and means for operating the cylinders simultaneously.

2. In a gold-washing machine having a series of reservoirs in its bed, a large cylinder in one of the reservoirs, a shaker-box in the reservoir, atrip-wheel on the spindle of the cylinder, a lever pivoted to the side of the frame of the machine and having an antifriction roller in its free end; said roller ad apted to engage the trip-wheel, a guide also secured to the frame for the lever, a second lever fulcrumed to the first-named lever near its pivoted end, said last-named lever being pivotally secured to the shaker-box at its lower end, as and for the purpose described.

3. In combination, a frame having an elongated reservoir at one end, a second reservoir at the opposite end, and a series of reservoirs approximately midway of its length, double bed-plates secured to the frame between the reservoirs, a hollow metal cylinder over the elongated reservoir, means for magnetizing the surface of the cylinder, a concaved scraper secured to the sides of the frame having one edge bearing against the cylinder, cylinders having perforated plates on their surfaces over the series of reservoirs, a larger cylinder having a perforated plate on its surface in the remaining reservoir, a shaker-box in the reservoir, a plate passing under the larger cylinder and entering the shaker-box, means for tripping the shaker-box and means for operating the cylinders simultaneously.

4. In combination, a frame having an elongated reservoir at one end, a second reservoir at the opposite end, and a series of reservoirs approximately midway of its length, double plates secured to the frame between the reservoirs, a hollow metal cylinder over the elongated reservoir, a concaved scraper secured to the sides of the frame and having one edge bearing against the cylinder, means for magnetizing the surface of the cylinder, cylinders having perforated plates on their surfaces ,over the series of reservoirs, a larger cylinder having a perforated plate on its surface in the remaining reservoir below the plane of the other cylinders, a shaker-box in the reservoir, a plate secured atone end of the frame passing under the cylinder and having a flared end entering the shaker-box, a tripwheel on the spindle of the large cylinder, a lever pivoted to the side of the frame and having its free end engaging the trip-wheel, a second lever fulcrumed at one end to the first-named lever and secured at the other end pivotally to the shaker-box, means for adjusting the cylinders and means for operating the cylinders simultaneously.
